Now its will shows you all network adaptors like LAN,Wifi,Blutooth,etc.,

Right click on the wirless network connection ,Click properties,now tick the chekbox "Show icon in the notification area when connected "

Now refresh your network list available or search a network ,If the network is security enabled means it will promt you to enter the password or key given by your network manager.
Thats it .
If you have any doubts feel free to ask me.I will help you by providing screenshots.

+1. Thank you, I had discovered this. I am not sure that it will remember this password, and am too bust right now to shut down my computer. Do I have to do this every time I log on, or will it remember the new password?

While entering your security key or password you will be prompt to enter twice in the first time, then tick the check box "remember my password" option.

Thanks, but no wifi icon. How else can I find the network manager? If I go to properties for my connection and go to the ssid page, there is no way to add or change a password, so I must be in the wrong place.

I think I found out how to add the icon. I remember I removed it some time ago. I am not at mu location now, but will try it when I am. Thanks.
